I was just going to play with them, nothing important.
First thing that comes to mind is: I was going to put them in a DAW and analyze to check if the audio truly is uncompressed as is (or if it was compressed before being sampled into its current format).

...prob nothing I couldn't do by converting it to little endian but I wanted to keep the audio stream untouched.

(Disclaimer: I don't know what a DAW is.)
I wanted to know why (or if) you expect that the software (or hardware) you want to use with the rifx wave files would be able to read such a very unusual format?
